SLUBBER, INTERMEDIATE, AND FINE FRAME DDEE-GOVERNOR.

To all whom it may concern:

Be it known that I, GEORGE R. KINDRICK, a citizen of the United States7residing at Spray, in the county of Rockingham and State of NorthCarolina, have invented a new and useful Slubber, Intermediate, and FineFrame DofPGovernor, of which the following is a specification.

This invention has reference to improvements in dott' governors beingdesigned to cause the same sized bobbins to be produced on every doti'and on all frames of the same size which run the same hank roving. iThis results in causing the succeeding frame to creel evenly thoughroving maybe used from several preceding frames in one creel.

The invention will be best understood from a consideration of thefollowing detail description taken in connection with the ac oompanyingdrawings forming a part of this specification, in which drawings,-

Figure 1 is an elevation of the governor forming the subject matter ofthe present invention. Fig. 2 is an elevation of the structure shown inFig. 1 but viewed from a position at right angles to the showing ofFig. 1. Fig. 3 is a perspective view of the upper portion of thegovernor with so much of a slubbing machine as is necessary to show therelation of the governor thereto. Fig. 4 is a section on the line A-B ofFig. 1 but drawn to a larger scale.

A portion of a slubbing machine is illustrated in Fig. 3, but the onlypart which need be referred to is the knock-ott' lever 1 of the slubberand a reciprocating member 2. These are colnmon parts of existingniaehines and need no description.

The governor forming the subject matter of the present invention is astructure designed to be secured by screws or bolts to the floor or asuitable support beneath the frame of the slubber so as to hold theknockoff lever of the slubber against action except at predeterminedtimes when,such lever is released automatically.

The governor comprises an upright frame or standard 3 which may beformed with or have secured to it a foot or base l designed to beattached to the floor upon which the frame of the slubber is supported.Near the upper end of the frame or standard there is secured an arbor 5having mounted on the end remote from the standard a lever G to thelower end of which is secured a plate 7 by means of bolts 8, extendingSpecification of Letters Patent.

through a slot 9 in the plate so that the plate 7 may be secured in anyposition of longitudinal adjustment with relation to the lever (3permitted by the length of the slot S) and the position of the bolts 8.The plate 7 is provided with an elongated slot 1() having an angularportion 11 displaced to one side of the longitudinal plane of the slotso that the end portions of the slot are in line one with the otherwhile the intermediate portion is composed of two like angularly relatedparts merging into the end portions of the slot and meetingintermediately.

Mounted on the arbor 5 is a ratchet wheel 12 held on the arbor between acollar 13 and washer 15 which latter is held against one face of theratchet wheel 13 by a spring 16 surrounding said arbor and held in placeby a washer 17 and pin 18 which latter traverses the arbor. By thismeans the ratchet wheel 12 is held against accidental movement on thearbor but may be rotated thereon by the application of a suitable power.The ratchet 12 carries a pin or stud 19 having a beveled end 2Oprojecting beyond one face of the ratchet wheel near the peripherythereof.

The upper end of the lever 6 extends above the arbor 5 for a sutlicientdistance and there carries a pawl 21 shown as a gravity pawl, but itwill be understood that if desired this pawl may be urged actively by asuitable spring. The pawl 21 is in operative relation with the teeth ofthe ratchet wheel 12 so that when the lever G is turned about the arbor5 in one direction the'pawl will engage the wheel 12 and rotate it asuitable distance and when the lever (3 is rocked in the other directionthe pawl will ride idly over the teeth of the ratchet wheel.

Mounted on the post or support 3 is a pawl 22 in position to engage theteeth of the ratchet wheel 12 and operate as a backstop pawl therefor.This pawl is under the normal control of a spring 23 one end of which isattached to the pawl at the end remote from that engaging the ratchetwheel and the other end of the spring is attached to the post or support3. Pivoted to the post or support 3 by means of a pivot pin or bolt 244is a lever 25 extending upward above the top of the post or support 3and there car1 \'ing an adjustable member 2G having a shoulder 27 at itsupper end, the

said member 26 being adjustable longitudinally of the lever 25. Theother end of the lever is under the normal control of the spring 28 fastat one end to the lower end of the lever and at the other end to thepost or support 3, the tendency of the spring being to maintain thelever 25 in substantial alinement with the post or support 3. The lever25 carries a pin 28 having one end beveled for engagement with thebeveled end 2O of the stud 19 and this pin is held to the lever 25 by aset screw 29 so as to be readily adjusted to different positions.

The relation of the pin 28 to the stud 19 is such that at everyrevolution of the ratchet wheel 12 the stud 19 will ride against thebeveled end of the pin 28 and so force the shoulder end of the lever eX-tension 26 to one side, the pin 28 being on the same side of the pivotbolt or pin 24 as is the shoulder 27.

The movable member 2 of the machine carries a pin 30 engaging in theslots 10, 11. So long as the pin 80 is at either end of the slot 10 theplate 7 and with it the lever 6 is held in the inactive position but assoon as the pin reaches one inclined portion 11 of the slot 10 then theplate 7 and the lever 6 are turned about the arbor 5 as a pivot in adirection, considering the pin 30 to be moving downward from the upperyend of the plate, to cause the pawl 21 to actively engage the ratchetwheel 12 and turn the same a distance equal to the length of one toothand as soon as the other portion 11 of the slot is reached the lever 6is returned to its original position, t-lie pawl 21 riding idly over theteeth of the ratchet wheel.

In the operation of the machine to which the attachment of the presentinvention is applied the member 2 reciprocates through a vertical path,and there is caused the winding of a layer upon a bobbin on eachmovement of the member 2 in either direction. The winding of thematerial on the bobbin continues so long as the weight member 1 is inthel elevated position and when this member drops the winding ceases.

l ith the attachment forming the subject matter of the presentinvent-ion the weight member 1 ,is upheld by engagement with theshoulder 27 of the extension 26 of the lever 25, this shoulderunderriding the weight. On each complete movement of the pin 30 ineither direction with the member 2 the ratchet wheel 12 is moved adistance of one tooth and this movement continues until the pin 19 isbrought into engagement with the pin 28 when the lever 25 is moved bythe cam action of the beveled end 20 of t-lie stud 19 with the beveledend of the pin 28 and the shoulder 27 is moved from under the weightmember 1 and the latter falls, thus throwing olf or stopping the windingof the material on the bobbins. Since the ratchet 12 is moved a distanceof one tooth for each layer produced upon the bobbins and since theratchet wheel must make one complete rotation in order to cause amovement of the lever 25 sufficient to carry the shoulder 27 fromengaging relation to the weight member 1, it follows that the number oflayers produced on a bobbin will depend upon the number of teeth in theratchet wheel 12. By varying this number of teeth and correspondinglyvarying the throw of the lever 6 the ratchet wheel 12 may be given acomplete rotation on a lesser or greater number of oscillations of thelever G and a correspondingly lesser or greater number of layers will beproduced on the bobbins. By this means there will always be produced onthe bobbins a predetermined number of layers and therefore thesucceeding frame will creel evenly though the roving be used fromseveral preceding frames in the one creel.

r)The doff governor after having been once applied and adjusted needs nofurther attention and does not require winding or setting since it worksentirely automatically. The power required to operate it is so small asto be unnoticeable in the operation of the machine. In order to resetthe device it is only necessary to elevate the weight member 1 when theshoulder portion 27 of the eXtension 26 of the lever 25 will move underthe weight member in engaging relation thereto, being constrained tothis movement by theV spring 28.

The dolip governor, being driven exclusively by the carriage isindependent of changes caused by fractional variations in.

the weight of the material treated, or by weather or other conditions.
